AWSRekognitionCompareFacesResponse

@interface AWSRekognitionCompareFacesResponse
  • An array of faces in the target image that match the source image face. Each CompareFacesMatch object provides the bounding box, the confidence level that the bounding box contains a face, and the similarity score for the face in the bounding box and the face in the source image.

    Declaration

    Objective-C

    @property (readwrite, strong, nonatomic)
        NSArray<AWSRekognitionCompareFacesMatch *> *_Nullable faceMatches;

    Swift

    var faceMatches: [AWSRekognitionCompareFacesMatch]? { get set }
  • The face in the source image that was used for comparison.

    Declaration

    Objective-C

    @property (readwrite, strong, nonatomic)
        AWSRekognitionComparedSourceImageFace *_Nullable sourceImageFace;

    Swift

    var sourceImageFace: AWSRekognitionComparedSourceImageFace? { get set }
  • The value of SourceImageOrientationCorrection is always null.

    If the input image is in .jpeg format, it might contain exchangeable image file format (Exif) metadata that includes the image’s orientation. Amazon Rekognition uses this orientation information to perform image correction. The bounding box coordinates are translated to represent object locations after the orientation information in the Exif metadata is used to correct the image orientation. Images in .png format don’t contain Exif metadata.

    Amazon Rekognition doesn’t perform image correction for images in .png format and .jpeg images without orientation information in the image Exif metadata. The bounding box coordinates aren’t translated and represent the object locations before the image is rotated.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic)
        AWSRekognitionOrientationCorrection sourceImageOrientationCorrection;
